Certainly the stand out piece in the Giambattista Valli x H&M collaboration. As seen on Kendall Jenner. 

NEW with tags - SOLD OUT. Rare, seen on literally everyone including on the show Emily in Paris. This is a size FR 34. I also have another one in a larger size listed as well.

Asymmetric dress in sturdy, pleated tulle. Deep V-neck with several layers of wide flounces at the top, a tapered waist with a seam trimmed with narrow grosgrain, and a short, super-flared skirt at the front. The skirt is long at the back with several layers of tulle for added width and volume. Reinforcing grosgrain waistband with an adjustable fastening on the inside for a firmer fit around the waist. Concealed zip at the back. Partly lined in a silk and cotton weave.
